We’ve all seen the ads. Some offer “free” solar panels. Others promise nearly free energy if you just purchase a solar — well, solar system doesn’t sound right — maybe… solar energy setup. Many of these plans are dubious at best. You pay for someone to mount solar panels on your house and then pay them for the electricity they generate at — presumably — a lower cost than your usual source of electricity. But what about just doing your own set up? Is it worth it? We can’t answer that, but [Brian Potter] can help you answer it for yourself.

In a recent post, he talks about the rise of solar power and how it is becoming a large part of the power generation landscape. Interestingly, he presents graphs of things like the cost per watt of solar panels adjusted for 2023 dollars. In 1975, a watt cost over $100. These days it is about $0.30. So the price isn’t what slows solar adoption.

The biggest problem is the intermittent nature of solar. But how bad is that really? It depends. If you can sell power back to the grid when you have it to spare and then buy it back later, that might make sense. But it is more effective to store what you make for your own use.

That, however, complicates things. If you really want to go off the grid, you need enough capacity to address your peak demand and enough storage to meet demand over several days to account for overcast days, for example.

There’s more to it than just that. Read the post for more details. But even if you don’t want solar, if you enjoy seeing data-driven analysis, there is plenty to like here.

Building an effective solar power system is within reach of nearly anyone these days. Some of the problems with solar go away when you put the cells in orbit. Of course, that always raises new problems.

Here at Hackaday, it’s a pretty safe bet that putting “World’s smallest” in the title of an article will instantly attract comments claiming that someone else built a far smaller version of the same thing. But that’s OK, because if there’s something smaller than this nearly microscopic LED blinky build, we definitely want to know about it.

The reason behind [Mike Roller]’s build is simple: he wanted to build something smaller than the previous smallest blinky. The 3.2-mm x 2.5-mm footprint of that effort is a tough act to follow, but technology has advanced somewhat in the last seven years, and [Mike] took advantage of that by basing his design on an ATtiny20 microcontroller in a WLCSP package and an 0201 LED, along with a current-limiting resistor and a decoupling capacitor. Powering the project is a 220-μF tantalum capacitor, which at a relatively whopping 3.2 mm x 1.6 mm determines the size of the PCB, which [Mike] insisted on using.

Assembling the project was challenging, to say the least. [Mike] originally tried a laboratory hot plate to reflow the board, but when the magnetic stirrer played havoc with the parts, he switched to a hot-air rework station with a very low airflow. Programming the microcontroller almost seemed like it was more of a challenge; when the pogo pins he was planning to use proved too large for the job he tacked leads made from 38-gauge magnet wire to the board with the aid of a micro hot air tool.

After building version one, [Mike] realized that even smaller components were available, so there’s now a 2.4 mm x 1.5 mm version using an 01005 LED. We suspect there’ll be a version 3.0 soon, though — he mentions that the new TI ultra-small microcontrollers weren’t available yet when he pulled this off, and no doubt he’ll want to take a stab at this again.

Warner Bros. Discovery has removed the entire lineup of classic Looney Tunes shorts (1930-1969) from its streaming service, Max. The company confirmed the move to Deadline, saying the streamer will prioritize adult and family programming, rather than content for kids.

This comes after Warner Bros. Discovery yanked hundreds of Looney Tunes episodes at the end of 2022, and later erroneously included the series in its list of titles leaving the platform. At the time, the company said Looney Tunes “will continue streaming on Max.” Newer Looney Tunes content, like Looney Tunes Cartoons released in 2020 and 2015’s New Looney Tunes, remains on Max.

Max didn’t immediately respond to The Verge’s request for comment.

Tons of content has been on the chopping block following David Zaslav’s takeover of Warner Bros. Discovery. Along with Looney Tunes, Warner Bros. Discovery ended its deal to stream Sesame Street on Max last year, and also replaced Cartoon Network’s website with a link to sign up for its streaming service. Warner Bros. Discovery also canned its Coyote vs. Acme film starring John Cena.

Despite this, the nearly-canceled Looney Tunes spinoff The Day the Earth Blew Up made its way to theaters over the weekend thanks to Ketchup Entertainment buying the distribution rights from Warner Bros. Discovery.
